defmodule LiterateCompiler.CLI do

Purpose

This module is the actual CLI for the escript

It does 3 things:

• prints the help
• displays the errors when the command is wrongly invoked
• runs the script

It uses the Elixir Standard Args library to process the arguments

  alias LiterateCompiler.Args
  alias LiterateCompiler.Outputter
  alias LiterateCompiler.ProcessFiles
  alias LiterateCompiler.Tree
  alias LiterateCompiler.TOC

Public API

  def main(args) do
    parsedargs = Args.parse_args(args)
    run(parsedargs)
  end

Private Fns

  defp run(parsedargs) when parsedargs.help do
      Args.print_help()
    end
  defp run(parsedargs) when parsedargs.errors != [] do
      Args.print_errors(parsedargs)
      IO.puts("run ./literate_compiler -h for help")
  end
  defp run(parsedargs) when parsedargs.print_files do
      Tree.walk_tree([parsedargs.inputdir], &ProcessFiles.list_file/1)
    end
  defp run(parsedargs) do
      files = Tree.walk_tree([parsedargs.inputdir], &ProcessFiles.process_file/1)
      :ok = Outputter.write_output(files, parsedargs)
      case parsedargs.make_jekyll do
        true  -> jekyll = Tree.walk_tree([parsedargs.inputdir], &ProcessFiles.make_jekyll_contents/1)
                 TOC.make_toc(jekyll, parsedargs)
        false -> :ok
      end
      :ok
  end
